With today's news of Gal Gadot being cast as Wonder Woman in the still untitled Batman vs. Superman movie, speculation can now turn to who will be the main antagonist in the film.

It's already been reported in that same announcement from Variety that Warner Bros. is looking at 300: Rise of an Empire and Zero Dark Thirty actor Callan Mulvey for the villain role but no word as to whom it is. Well, according to our sources here at ThinkMcFlyThink, the villian role Mulvey is being considered for is none other than...Metallo.

That's right, the man with the sheilded metal body and Kryptonite for a heart is said to be the main baddie in Batman vs. Superman.
